TECHNICAL FIELD

The present disclosure relates to the technical field of furniture, in particular to a secondary combustion structure of a smokeless stove.

BACKGROUND ART

A stove is used for warming and cooking. In daily use, the stove usually generates a large amount of smoke, and the room will be full of smoke smell. When the smoke smell is serious, even the room cannot stay, and people need to open the window for ventilation, but this will influence the function of the stove. However, the main reason for the generation of smoke is the closed structure at the bottom of the traditional stove, which causes less oxygen intake and insufficient fuel combustion, so white smoke-grade carbon monoxide is generated.

Therefore, there is an urgent need to design a secondary combustion structure of a smokeless stove to overcome the deficiencies of the prior art.

The technical solution used by the present disclosure for achieving the above technical objective is as follows: a secondary combustion structure of a smokeless stove includes: a stove body, where the stove body is hollow, a combustion disc for accommodating a combustible is arranged in the stove body, several separated first ventilation holes are provided in the combustion disc, an inner wall is further vertically arranged in the stove body, the inner wall is separated from a side wall of the stove body to form a heating chamber, several separated second ventilation holes are provided in a top of the inner wall, an air inlet hole is further provided in a bottom of the stove body, and a top of the stove body is inclined towards the inner wall at a preset angle.

In one preferred embodiment, a base is further arranged at the bottom of the stove body, a protruding boss is arranged in the middle of the base, and the air inlet hole is provided in a side wall of the base.

In one preferred embodiment, the side wall of the base is inclined outwards.

In one preferred embodiment, the boss has a trapezoidal cross section.

The present disclosure has the beneficial effects: the vertical inner wall is arranged in the stove body, the heating chamber is defined between the stove body and the inner wall, and the second ventilation holes are provided in the top of the inner wall, such that heated air flows out of the second ventilation holes to support combustion of combustible gas, further secondary combustion is achieved, a combustible is combusted more sufficiently, and smoke is reduced; and moreover, a top of the stove body is inclined towards the inner wall, so as to increase a flow speed of the heated gas, and increase a fire behavior of the combustible.

DETAILED DESCRIPTION OF THE EMBODIMENTS

To make the foregoing objective, features, and advantages of the present disclosure clearer and more comprehensible, the specific implementation modes of the present disclosure will be described in detail below in conjunction with the accompanying drawings. Numerous specific details are set forth in the following description to facilitate a thorough understanding of the present disclosure. However, the present disclosure can be practiced in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the spirit of the present disclosure, and therefore the present disclosure is not to be limited by the specific embodiments disclosed below.

As shown in FIGS. 1-4 , the present disclosure provides a secondary combustion structure of a smokeless stove. The secondary combustion structure includes: a stove body 10, where the stove body 10 is hollow, a combustion disc 11 for accommodating a combustible is arranged in the stove body, several separated first ventilation holes 111 are provided in the combustion disc 11, an inner wall 101 is further vertically arranged in the stove body 10, the inner wall 101 is separated from a side wall of the stove body 10 to form a heating chamber 12, several separated second ventilation holes 102 are provided in a top of the inner wall 101, an air inlet hole 105 is further provided in a bottom of the stove body 10, and a top of the stove body 10 is inclined towards the inner wall 101 at a preset angle. Specifically, external air flows into the stove body 10 from the air inlet hole 105, part of the external air flows out by means of the first ventilation holes 111 of the combustion disc 11 to assist combustion of a combustible located on the combustion disc 11, the combustion is the primary combustion, the other part of the external air flows into the heating chamber 12 between the stove body 10 and the inner wall 101, when the combustible is combusted, the inner wall 101 is heated to heat the air in the heating chamber 12 to generate hot air, the hot air rises and gathers at the top of the heating chamber 12 and flows out of the heating chamber 12 by means of the second ventilation holes 102 to enter a space where the combustion disc 11 is located, such that the unburned combustible gas of the combustible is combusted by means of flame retardance of the air, the combustion is secondary combustion, so as to achieve sufficient combustion of the combustible and reduce smoke, in addition, the top of the stove body 10 is inclined towards the inner wall 101, and an inclination angle is 4°, such that the heating chamber 12 is a conical air channel with an upper portion smaller than a lower portion, when air is heated under an influence of the temperature of the inner wall 101, the air rises to the top of the heating chamber 12 and is limited by the space at the top of the heating chamber 12, continuous rising of the hot air accelerates a flow speed of the air and increases a speed of the air flowing out by means of the second ventilation holes 102, the flow speed of the air influences the fire behavior of the combustible, and the higher the flow speed is, the larger the fire behavior is, such that the combustible may be combusted more fully.

Further, in this embodiment, a base 103 is further arranged at the bottom of the stove body 10, a protruding boss 104 is arranged in the middle of the base 103, and the air inlet hole 105 is provided in a side wall of the base 103. Specifically, the base 103 is further arranged at the bottom of the stove body 10, and the center of the base 103 is in an upward protruding shape, such that the center of the base 103 is separated from the ground, and the situation that a temperature is transferred to the ground when the combustible is combusted, and the ground generates high temperature is avoided.

Further, the side wall of the base 103 is inclined outwards. Specifically, the side wall of the base 103 is arranged to be inclined outwards, such that the air inlet hole 105 provided in the side wall is in an upward state, air entering by means of the air inlet hole 105 enters the stove body 10 in an upward inclined mode, moreover, the air enters the heating chamber 12 by means of limitation of the boss 104, the inflow amount and the flow speed of the air are increased, and the reduction of air flow amount and flow speed due to smooth inflow of the air is avoided.

Further, the boss 104 has a trapezoidal cross section. Specifically, the boss 104 has the trapezoidal cross section, such that a side wall of the boss 104 is inclined, when flowing in by means of the air inlet hole 105, the air impacts on the side wall of the boss 104, and the flow speed of the air entering is increased by means of slope setting of the side wall of the boss 104.

Therefore, the vertical inner wall is arranged in the stove body, the heating chamber is defined between the stove body and the inner wall, and the second ventilation holes are provided in the top of the inner wall, such that heated air flows out of the second ventilation holes to support combustion of combustible gas, further secondary combustion is achieved, a combustible is combusted more sufficiently, and smoke is reduced; and moreover, a top of the stove body is inclined towards the inner wall, so as to increase a flow speed of the heated gas, and increase a fire behavior of the combustible.

The present disclosure is not limited merely to what is described in the specification and the implementation modes, such that additional advantages and modifications can be readily achieved by those skilled in the art. Without departing from the spirit and scope of the general concept as defined by the claims and the equivalents, the present disclosure is not limited to the specific details, representative apparatus, and illustrative examples as shown and described herein.
